The output from the show storm-control privileged EXEC command shows the upper, lower, and
current thresholds as a percentage of the total bandwidth or the packets per second, depending on the
configuration.

Purpose
Configure broadcast, multicast, or unicast storm control.
For level, specify the rising threshold level for broadcast, multicast,
or unicast traffic as a percentage of the bandwidth. The storm control
action occurs when traffic utilization reaches this level.
(Optional) For level-low, specify the falling threshold level as a
percentage of the bandwidth. This value must be less than the rising
supression value.The normal transmission restarts (if the action is
filtering) when traffic drops below this level.
For pps pps, specify the rising threshold level for broadcast,
multicast, or unicast traffic in packets per second. The storm control
action occurs when traffic reaches this level. This option is supported
only on non-LRE Catalyst 2950 switches running Cisco IOS
Release 12.1(14)EA1 or later.
For pps-low, specify the falling threshold level in packets per second
that can be less than or equal to the rising threshold level. The normal
transmission restarts (if the action is filtering) when traffic drops
below this level. This option is supported only on non-LRE
Catalyst 2950 switches.
For pps and pps-low, the range is from 0 to 4294967295.
Specify the action to be taken when a storm is detected.
The default is to filter out the traffic and not to send traps.
Select the shutdown keyword to error-disable the port during a
storm.
Select the trap keyword to generate an SNMP trap when a storm is
detected.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
